Systems and methods for managing sanitization

Abstract

A mobile computing device monitors sanitization of an object by electro-optical (EO) radiation emitted by a sanitizer device. The mobile computing device determines the cumulative exposure based on a position and/or orientation of the sanitizer device relative to the object. The mobile computing device captures images of the object, and augments the image with graphical elements indicating a cumulative exposure of respective portions of the object by the EO radiation. The augmented images may be presented within a graphical user interface presented on a display of the mobile computing device.
